What do the map icons mean?
Higher air pollution snapshot means the tube was over the level at which the mean annual limit is set (40µg/m3)
Lower air pollution snapshot means the tube was under the level at which the mean annual limit is set (40µg/m3)
Local groups monitoring sites are the sites where our local groups have placed air monitoring tubes.
NB All the results from the diffusion tubes required calibration and adjusting alongside government figures. This is called a bias adjustment. We’ve spoken to experts in monitoring and have adjusted all the results for accuracy using a bias correction factor for the type of diffusion tube used.
